Title: Downhole fluid separation system
Inventor: LEE LAURENCE CHE-KEUNG
IPC: E21B43/38
Filed: 1997-06-25
Abstract: A downhole fluid separation system is used with submergible pumping systems to separate downhole fluids into different density fluids, recover the lighter fluids to the earth's surface, and dispose the heavier fluids downhole. The fluid separation system includes a plurality of housings connectable one to another, each housing having one or more fluid separators, such as hydrocyclones, therein with an inlet of each fluid separator in communication with an inlet conduit, an overflow of each fluid separator in communication with an overflow conduit, and an underflow of each fluid separator in communication with an underflow conduit. The fluid separation system can be configured for parallel flow where the conduits conveying fluids downstream of a first housing have a greater cross-sectional flow area than corresponding conduits in an adjacent second housing. Also, the fluid separation system can be configured for series flow, for either the separated lighter or the separated heavier fluids. The use of differing sized conduits in the housings as required for the actual flow rates in each housing enable higher flow capacity fluid separators to be used than previously possible for greater fluid handling efficiency.

Title: Transdermal therapeutic system identified without printing inks and process for manufacturing the same
Inventor: HORSTMANN MICHAEL
IPC: A61L15/44
Filed: 1996-04-23
Abstract: A transdermal therapeutic system is disclosed to administer active substances through the skin to the human body. The backing layer consists of pharmaceutically usual plastic foil laminates made of thermoplastic materials that melt at a low temperature on its outer side and of thermoplastic materials that melt at a higher temperature facing the skin. The backing layer needs to be identified, for example by printing. Using pigments or lacquers for printing creates problems, however, because of their toxicological and technological inconvenients, as well as legal restrictions that apply to medicaments. According to the invention, therefore, the identification code does not consist of a dye or pigment layer, but of a modification of the surface structure of the backing layer that corresponds to the identification code.

Patent CA-2230304-A1 (CA)
Inventor: CSINGER ANDREW
IPC: H04L9/32
Filed: 1998-02-23
Abstract: In an exemplary embodiment, the server receives the client's Distinguishing Name (DN), and then searches its directory for identification information and access control rights for this specific context. The server can act as a stand-alone server or in conjunction with other directory services on the network. A client must have a verifiable identity in order for secure communications to continue. A client's identity can be said to be fully verifiable if the server has access to the directory service that maintains that client's DN. The client receives the server's DN, and the client can then determine whether or not to accept a response to a request for information (i.e., trust the response). The client determines the identity of the server using some directory service (the client can act stand-alone or as a client of other directory servers). A server is fully verifiable if the client can identify the directory service that maintains the server's DN. In both cases, determining identity is predicated on being able to identify a directory service. Since servers and clients are issued identities (DN's) from some directory service before they participate in secure communications, they are able to at least identify their "home" directory service. Their "home" directory service communicates with other directory services, each "serving" their lists of electronic identities to each other using secure directory services. In this manner, a client or server can verify the peer identity of a secure communicator by relying on the trusted "home" directory service. Public Key certificates, certificate revocation lists, pending certificate requests, Certification Authority policy, and other information is stored in the directory server. Access to the directory server is through secure communications; this maintains the integrity and privacy of the information.

Title: Process for treating metal oxide fines
Inventor: HORNE DEANE A
IPC: C22B1/24
Filed: 1996-03-27
Abstract: The present invention provides for a process for recovering elemental iron by treating metal oxide fines including oxide therein. The process includes combining the metal oxide fines with a carbonaceous material containing more than about 20 wt% volatile matter to form a mixture. The mixture is agglomerated under conditions sufficient to mobilize the volatile matter to function as a binder that bonds the mixture to form green compacts. The green compacts are heated for a time and at a temperature sufficient to reduce the iron oxide to elemental iron. The carbononaceous material functions as a reductant for the iron oxide.

Abstract: A separator for separating material from an air flow, has a plenum chamber to which the air and material are fed. A rapid decrease of air velocity occurs in the plenum chamber and much of the material separates out due to gravity.      The air impinges on a deflector and further separation occurs.      A diffuser can be used to prevent localized high velocity air streams occurring. At low rates of material content excess air flow can cause carrying over problems. An air throttle can be provided to restrict air flow velocity increases in high air flow conditions.

Title: Addition of salts to improve the interaction of silica with rubber
Inventor: COLE WILLIAM M
IPC: C08K3/36
Filed: 1998-07-06
Abstract: Incorporation of neutral water soluble inorganic salts into a precipitated silica improves the filler  dispersion  in  a  compounded  rubber,  reduces rolling   resistance    (hysteresis),    and   improves processability. These properties are achieved without loss of the expected reinforcement effect due to the substitution of inorganic salt for SiO2 in the silica. The properties are seen when a variety of silanes and processing aids are added to the silica.
